Connecting Cables
100BASE-T Ethernet Network
The RJ-45 port on the PRE is configurable for 100-Mbps full-duplex or half-duplex operation
(half-duplex is the default) and supports IEEE 802.3, Ethernet, and IEEE 802.3u interfaces compliant
with 100BASE-T specifications.
Caution If the Cisco uBR10012 router is used in an environment in which lightning-induced transients are likely
to couple to the signal lines, use of shielded interconnection cables for the 100BASE-T ports is highly
recommended. In addition, use of shielded interconnection cables for the 100BASE-T ports is required
to meet Telcordia GR1089 CORE Section 4.5.9 and ETSI Section 5.2.2.2 (intra-building lightning
surge).
To connect the PRE to a 100BASE-T Ethernet LAN:
Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled Ethernet.
Step 1
Run the cable up and through the cable management bracket and connect the other end of the Ethernet
Step 2
cable to any unoccupied port on the Ethernet hub.
Tip When power is applied to the chassis, check the LNK (Link) LED on the PRE faceplate port next to the
Ethernet port. This LED illuminates (green) if the PRE is correctly connected to the Ethernet LAN.

is required.
Beginning with Cisco IOS Release 12.2(15)BC2, Cisco now supports IF muting with non-SNMP
upconverters. In previous releases, IF muting was not available for non-SNMP upconverters and this
limited the availability of N+1 redundancy in some circumstances. For additional information about IF
muting and N+1 redundancy, refer to N+1 Redundancy for the Cisco Cable Modem Termination System
